PRECAUTIONS: READ THIS BEFORE OPERATING YOUR UNIT
s To assure the finest performance, please read this manual carefully. Keep it in a safe place for future reference. s This unit is equipped with the newly developed Active Servo Processing Speaker System. It is not designed for use with conventional speakers. Therefore, do not attempt to connect other speakers than the provided speaker system. s Choose the installation location of this unit carefully. Avoid placing it in direct sunlight or close to a source of heat. Also avoid locations subject to vibration and excessive dust, heat, cold or moisture. Keep it away from sources of hum such as transformers and electric motors. s Do not operate this unit upside-down. It may overheat, possibly causing damage. s Never open the cabinet. If something drops into the set, contact your dealer s Do not place CD or other objects on top of this unit. s Do not use force on switches, controls or connection wires. When moving the unit, first disconnect the power plug and the wires connected to other equipment. Never pull the wire itself. s Do not attempt to clean the unit with chemical solvents; this might damage the finish. Use a clean, dry cloth. s Be sure to read the TROUBLESHOOTING section regarding common operating errors before concluding that the unit is faulty. s To prevent lightning damage, disconnect the AC power plug and disconnect the antenna cable when there is an electrical storm. s Do not plug the AC power plug to the wall socket before you finish all connections. s Never allow metallic items (e.g. screwdrivers, tools, etc.) to come near the cassette decks record/playback head assembly in this unit. Doing so may not only scratch or damage the heads mirrorsmooth finish, it may change the magnetic characteristics of the heads, causing a deterioration in reproduction performance quality. s Although the cassette decks record/playback heads used in this unit are high quality heads with outstanding reproduction characteristics, they can become dirty through the use of old tapes or from dust accumulation over time. This can have a serious effect on reproduction quality. Clean the heads regularly with one of the commonly available head cleaners or with cleaning solutions. s The voltage to be used must be the same as that specified on this unit. Using this product with a higher voltage than that which is specified is dangerous and may result in a fire or other type of accident causing damage. YAMAHA will not be held responsible for any damage resulting from use of this unit with a voltage other than that which is specified. s Sudden temperature changes and storage or operation in an extremely humid environment may cause condensation inside the cabinet. Condensation can cause the unit to malfunction. Follow the procedure below to eliminate condensation. If this units operation freezes or display indications are incorrect First disconnect the AC supply lead from the wall AC outlet, and then press the RESET button on the rear of this unit at least for one minute. This operation resets the internal microcomputer which controls this unit. However, this operation will also erase all memorized broadcasting stations. To store stations again, follow the methods described on page 1920. STANDBY mode While the power is on, pressing the POWER switch (or the POWER button on the remote control transmitter) switches the unit to the STANDBY mode. (In this mode, the indicator above the POWER switch illuminates.) In this mode, main voltage is still present inside the unit. If you want to switch off the unit completely, disconnect the AC power plug from the wall socket.

Thus it is this problem that is resolved through the employment of a design in which the amplifier functions to supply the signals. If the electrical resistance of the voice coil is reduced to zero, the movement of the speaker unit would become linear with respect to signal voltage, and, to accomplish this, a special negative-impedance output-drive amplifier for subtracting output impedance of the amplifier is used. By employing negative-impedance drive circuits, the amplifier is able to generate precise, low-amplitude low-frequency waves with superior damping characteristics, and these waves are then radiated from the cabinet opening as highamplitude signals. The system can, therefore, by employing the negative-impedance output drive amplifier and a speaker cabinet with the Helmholtz resonator, reproduce an extremely wide range of frequencies (28 Hz 20 kHz) with amazing sound quality and less distortion. The features described above, then, are combined to be the fundamental structure of the Active Servo Technology.
